Interface IColorGlyphRenderer

Namespace

Egami.Drawing

Assembly

Egami.Drawing.dll

Draws color glyphs of a format Egami.Drawing does not draw itself, such as the SVG documents of an OpenType SVG table (Egami.Svg's SvgGlyphRenderer). Set on ColorGlyphRenderer, it is asked first for every glyph whose font has that format, except where the font has a COLR version 1 glyph, so the order is COLR v1, the renderer, COLR v0, sbix, CBDT, then the outline.

public interface IColorGlyphRenderer

Examples

// Emoji and other glyphs from an OpenType SVG table draw in color on a canvas given the renderer.
using (RasterCanvas<Rgba8> canvas = raster.CreateCanvas(new CanvasOptions { ColorGlyphRenderer = SvgGlyphRenderer.Instance }))
{
    canvas.DrawText("Hello", new System.Numerics.Vector2(10, 35), font, new SolidPaint(new RgbaF32(0, 0, 0, 1)));
}

Methods

TryDraw(Canvas, Font, ushort, Matrix3x2, Paint)

Draws one glyph, or returns false when the font has nothing of the renderer's formats for it.

Parameters

canvas Canvas

The canvas to draw on.

font Font

The font, at its size.

glyph ushort

The glyph id.

transform Matrix3x2

Maps the glyph's space (its origin on the baseline, the font's size, y down) into the canvas's local coordinates.

paint Paint

The text's paint: its color is the foreground some glyphs draw in.

Returns

bool
